Values are presented as mean ± standard deviation.
ROI, region of interest; PD, panic disorder; HCs, healthy controls; ES, effect size.
a
No significant between-group effect was found in volumes of the left hippocampal ROIs (F = 0.52, p = 0.674, ηp 2 = 0.027). b There was a significant between-group effect in volumes of the right hippocampal ROIs (F = 6.88, p = 0.001, ηp2 = 0.269). c Statistical significances were corrected for multiple comparisons using a Bonferroni method. d ESs were calculated using partial eta squared (ηp2).
